An organism, individual, species, company, etc. can survive effectively via adaptive radiation into niches where there is less, little, or no competition. This is an effective strategy. However, at a certain point lack of competition leaves them vulnerable to another species, company etc. that has evolved under intense competition. There aren't any winners in steady state competition, that is, until your average run of the mill grey squirrel is introduced into regions (markets?) where the existing scatter gatherers didn't have any competition. Then they dominate and drive all the competition to extinction. Sometimes capital accumulation can let a non-competitive company survive the market entry of a competitor that operates more efficiently in a way that is similar to how a species with a large population might have a few members that can compete effectively. But at the end of the day those fat margins will eventually disappear.
